Summary: The low dielectric breakdown strength and poor thermal stability of BiFeO3-based relaxor ferroelectric ceramics have hindered their actual pulse capacitor application. In this work, nanodomain-engineered and grain-engineered BiFeO3-BaTiO3-CaTiO3 relaxor ferroelectric ceramics were manufactured to solve these issues. The introduction of CaTiO3 led to the formation of nanoscale domains, resulting in temperature-insensitive dielectric response and almost hysteresis-free polarization field response. Moreover, the refinement of the grain size and the depression of the oxygen vacancy concentration greatly enhanced the dielectric breakdown strengths. As a result, the ceramics exhibited remarkable energy-storage performances, high recoverable energy density, high efficiency, outstanding thermal stability, ultrafast release time, and high power density, indicating their enormous potential for pulse capacitor applications.

Summary: Rare earth doped ferroelectric ceramics, such as the x% mol Sm3+ doped BaTiO3 (BTO:xSm3+) ceramics studied in this research, have shown great potential for multifunctional optical-electro devices. The effect of Sm3+ ions composition on the phase structure, ferroelectric, energy storage, and photoluminescence properties were investigated. The results indicate that the addition of Sm3+ ions leads to a decrease in remanent polarization, but a significant increase in energy storage density and efficiency. The ceramics also exhibit a broader temperature transition range and a lower Curie temperature, making them suitable for optoelectronic device design.

Summary: When rare-earth ions are embedded in a ferroelectric material, their photoluminescence can serve as an all-optical probe for temperature, electric field, and mechanical stimulus. However, the impact of ferroelectric phase transitions on photoluminescence is not well understood. In this study, we demonstrate changes in the photoluminescence of green emission bands during critical ferroelectric transitions in an Er-doped BaTiO3 material. We also find that the intensity ratio and wavelength position difference of sub-peaks provide information on the phase transitions.

Summary: BaTiO3 doped GaFeO3 multiferroic ceramics were prepared and the influence of BaTiO3 doping on the properties of GaFeO3 ceramics was systematically studied. The results showed enhanced multiferroic behaviors in 0.9GaFeO3-0.1BaTiO3 ceramics compared with pure GaFeO3 ceramics. The increase in polarization and magnetic properties was attributed to the formation of BaFe12O19 phase. These ceramics show potential applications in information storage and magnetoelectric applications.

Summary: Magnesium and Niobium co-doped BaTiO3 ceramics were prepared, and their crystal structures, microstructures, valence states, and dielectric properties were studied. The study found that the lattice parameter of the ceramics increased with doping content, and thermal activation relaxation processes were observed. The analysis of electric modulus revealed that high-frequency relaxation was associated with the electrical properties of grain boundary, and the permittivity plateaus were related to the inhomogeneous structures of grain and grain boundary.

Summary: Mechanoluminescence (ML) has become increasingly popular in various fields over the past two decades. The materials capable of generating ML can be classified into self-powered and trap-controlled. In this study, we demonstrate that both self-powered ML and trap-controlled ML can be achieved simultaneously in MgF2:Tm3+. The material exhibits transitions from ultraviolet-C to near-infrared upon external force stimulation. Moreover, MgF2:Tm3+ shows stronger ML after exposure to X-rays and the ML returns to the initial level after high-temperature cleaning, indicating trap-controlled ML characteristics. Additionally, we explore the potential applications of MgF2:Tm3+ in dynamic anti-counterfeiting and structure inspection.

Summary: The substantial enhancement of multimode luminescence, including mechanoluminescence, photoluminescence, and X-ray excited optical luminescence, of Mn2+ and Tb3+ in zinc calcium oxysulfide (CaZnOS) is achieved by increasing the concentration of oxygen vacancies (OVs). It was found that CaZnOS lattice has a tolerance of 60% for Sr2+ substitution. The lattice distortion caused by Sr2+ incorporation can efficiently promote the elimination of oxygen and produce more OVs, leading to stronger luminescence.

Summary: Converting mechanical energy into photon emission has significant implications for intelligent sensing, self-powered lighting, and distributed energy harvesting. Understanding the dynamic process of intensity variation in mechano-to-photon conversion is challenging and requires a time-domain characterization scheme. By characterizing the mechanoluminescence decay, the dynamics of charge migration in ML materials can be revealed. This research also demonstrates the temperature dependence and stress fluctuation resistance of ML decay, which opens up new possibilities for self-powered and remote temperature sensing. Additionally, an ultrafast-response stress sensor utilizing ML sensing technology is developed.

Summary: A multifunctional sensing platform based on photoluminescence (PL) and mechanoluminescence (ML) is created by combining heterojunctioned ZnS/CaZnOS:Mn2+ mechano-photonic materials and fiber spinning. Flexible optical devices capable of emitting light driven by mechanical force are developed by embedding ML-active particles in micrometer-sized cellulose fibers using a 3D-printing technique. The platform allows low-pressure sensing up to 100 bar and demonstrates a superior high-pressure sensitivity of 6.20 nm GPa(-1) using the developed optical manometer based on the PL of the materials. Four modes of temperature detection are achieved using this platform.
